I love dim sum and dislike seafood, so I'm a big fan of Sun Sui Wah:

Although, like most Chinese restaurants, they have 'Seafood' in their name, they have many non-water-breather options.
Sun Sui Wah
3888 Main Street @ 23rd Avenue
Vancouver

Note that they're extremely popular & busy on weekends, so I would get there by 11am.
